Really sorry for the delay on this, especially as I've found one or two problems. The first problem is that with this vyasa-rk3288 and a few others fail to build due to a number of errors such as: ../common/spl/spl.c:269:12: error: 'struct spl_image_info' has no member named 'dcrc_data' Second, I believe this is causing a number of platforms with very tight SPL constraints, namely all of 64bit sunxi, to fail to link as they overflow SRAM now. This can be fixed at least by making the new behavior opt-in, but I would fix the vyasa-rk3288 problem first. Thanks in advance! -- Tom
